Hi,


the Loire-100 was a four engined transatlantic flying boat powered by four 630 hp Hispano-
Suiza 9V engines,mounted tandem in two pairs,and Loire-101 was also the same four engined
mounted in leading edge of wings,remained a Projects only.

I think they had the same fuselage,can anyone make a speculative drawings to them ?;

In response to the specification of 1934 for a seaplane intended for the
South Atlantic line, the office of studies Loire, still under the direction of
Yves Jan-Kerguistel, took over the formula of the Loire 70 and studied several
configurations which were distinguished by the arrangement of the engines. The
Loire 100 was a four-engine Hispano-Suiza 9V star of 630 hp, arranged in tandem
two in pairs on the canopy, while the Loire 101 had these same engines
in line on the leading edge. The first project was abandoned because it was
believed that the rear propellers were likely to touch the water if
heavy seas.

nevertheless the formula of the engines in tandem, but widely installed
above the wing, at the top of connecting chimneys which made them
accessible in flight. These engines had become Hispano-Suiza 12 Xbrs-1
of 720 hp. This configuration was called Loire 102. It was therefore a seaplane
hull, high wing monoplane, high

From, Конструкции металлических самолетов 1935,

the Loire-11,was under construction.

A promizing LN 600 carrier torpedo bomber flew successfully 35 hours before June 1940, a LN 20 fighter was build but never flew owing the choice of both Potez 630 and Bréguet 790 selections. But both were twin engined

No one heard about this,maybe he meant LN 400 ?.

From Ailes 1938/21/4,

what was this ?!.

Wasn't the single-seat fighter the Nieuport 60 and the seaplane the LN-60?

No Stargazer,the Nieuport 60 was a low-wing four engined bomber seaplane project,
of HB.4 designation,and the LN-60 as I know was a single seat fighter,but the site
which I mentioned it make me confuse.

Strange. Here is the Nieuport 60 that I know about:

I have been looking back at this and I think I have the answer. The profile is not of the Nieuport LX but the IX. The extra bit, I think, converting the I to L is an overprint error. For comparison here's a colour profile of the IX and the original posted GA profile which was thought to be the LX.

From, From, Revue_des_forces_aériennes 1929,

the Loire-10.

 

[hesham]

By the way,

in my new book,there are more than 70 items for Loire and Loire-Nieuport,
included main designs,variants and projects,can you imagine ?.

 

[PhR]

But since the LN-60 existed, there MUST have been a fifth Loire-Nieuport design before, hence hesham's legitimate question about the LN-50 slot...

This is not necessarily true, as these number alternate between two offices: LN-10 and LN-30 for Saint-Nazaire (ex Loire), LN-20, LN-40 and LN-60 for Issy-le-Moulineaux (ex Nieuport).
LN-60 became CAO-200. I don't have any trace of LN-50.

 

[PhR]

The Loire-Nieuport LN-560 and LN-561 was real designs and not a misprint,and why
they called 560 & 561 instead off 500 & 501,because they was based on the front of
fuselage of Models Loire-Nieuport 160 & 161.

I am skeptical on both explanations. I never heard about neither LN-560/561 nor LN-500/501. Where these projects designation are coming from? Do you have evidences?

Yes I have,

Les dernières études Loire-Nieuport furent les projets 560 et 561, avions de
bombardement en piqué destinés à recevoir un moteur Hispano-Suiza 12 Z
de 1 200 ch. Les événements de 1940 stoppèrent définitivement tout
développement de ces études.

I am still not convinced by the existence of such designation. "Les événements de 1940 stoppèrent définitivement tout développement de ces études", so, at that date, this is impossible to be a "LN" number. The only possibility is CAO, which replaced LN since 1937.
I never found any trace of such designation in the archives of the companies. In addition, on both Loire-Nieuport and SNCAO systems, the sequence starting by "5" was not assigned to Nieuport (specialist for dive bombers) but to Loire.

For me, this description may corresponds to the CAO 810 project.

As text mentioned,I think it was from Loire for developing aircraft based only on fuselages of Nieuport 160 & 161.

This photo has a better quality than the one I found.

Project of SNCAO CAO-810 nose-flying bomber (France. 1939).
The CAD-810 nose-dive bomber was to use either the 1200 hp Hispano-Suiza 12Y 89 engine or the 1300 hp turbocharged Hispano-Suiza 12Z. It will not have time to be developed.

Now that's what I call a French Stuka !

Hi

 

[PhR]

The main problem is the huge size of the remaining factory drawings of this project. It's already a great luck that they survived. Waroff did a great job.

It's great that these drawings have been preserved.

 

[pomkit]

I was able to acquire a copy of the drawing from Waroff. I made a four-view drawing that interprets what the SNCAO 810 could have looked like if it had been made at the time. Just a fantasy...
